Same as you, my favorite for handling (actually hiding) errors is IFERROR, or IF(ISERROR) before Excel 2010

Frankly, I have never encountered #NULL before, as I have never written a formula for intersection and I doubt how many regular users would do it in workplace.
But as you requested, here's one formula that returns #NULL
=sum(A1:B2 C3:D4)
Great podcast and Excel error resource post Chandoo! I will share this.
I created a video last year about using ERROR.TYPE function to distinguish between error types.

#NULL is easy to recreate. Simply write any formula that requires addition, subtraction, multiplication, or division and leave out the operator.
A1 = 1
A2 = 1
=A1+A2 = 2
=A1 A2 = #NULL
Off to the races.
